Glyph Hack Delay
Glyphing works as intended, but initiating the glyph hack has a small delay before the grid shows up (about a second). Before recursing, the grid showed up instantly. Recursing revealed that delay. It disappeared after reaching Level 5.
If an Agent is below Level 5, just initiating a glyph hack will cause a delay. There's no extra steps to it.

(I probably should've got a screen capture though.)
